It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a flowchart of a method for searching for a point of interest according to an embodiment of the present invention. The present embodiment is applicable to a case where an event related to a position is displayed in a map. The method may be performed by a point of interest searching apparatus, which may be implemented by software and/or hardware. Referring to fig. 1, the method for searching for a point of interest provided in this embodiment includes:

s110, obtaining search keywords currently determined by a user, wherein the search keywords comprise keywords of event information.

The event information is a description of the event, and the specific description form may be at least one of a text, a video and a picture. Events refer to historical and modern events that have occurred. The event may be a place where an earthquake occurs, a traffic accident occurs in a street, a place where a scene is viewed in a television show, a place where a historical event occurs, or the like.

Typically, events can be customized for the user based on their information.

Specifically, according to the user's favorite tv drama, the relevant eight diagrams events are customized for him, such as "place of leaving home of conconconcongxu", "place of visiting private of chengxing dynasty, Ming dao Ming dynasty" and the like. Discount offer information of a certain place shop which may be interested in the discount offer information can also be customized into an event according to the interest of the user.

Optionally, the determining manner of the search keyword by the user may be implemented by a manual input manner, or may be implemented by selecting a history keyword, which is not limited in this embodiment.

And S120, matching the keywords of the event information with the prestored interest points.

Wherein the points of interest comprise virtual points of interest of an event. As described above, the event is location dependent.

Specifically, there may be a plurality of rules for matching the keywords of the event information with the event information associated with the pre-stored virtual interest points. When one keyword of the event information exists, taking the virtual interest point containing the keyword in the event information as an interest point which is successfully matched; and when the event information has a plurality of keywords, taking the virtual interest points of the event information containing at least one keyword as the interest points successfully matched, or taking the virtual interest points of the event information containing all the keywords as the interest points successfully matched. The determination of the matching rule may be set as desired.

And S130, displaying the interest points successfully matched in the map.

Optionally, the display mode of the successfully matched virtual interest point in the map may be the same as or different from the display mode of other interest points in the prior art.

Typically, to facilitate the user's viewing of the event, the successfully matched points of interest are displayed in a map, including:

The summary information of the event can be extracted from the detailed information of the event, which is the event information.

Specifically, the summary information may be composed of a picture and/or a sentence summarized at the center of the sentence.

Through the hierarchical display mode that the abstract of the event is displayed firstly and then the detailed information of the event is displayed, a user can quickly look up the event through the abstract. After the event is determined to be the interesting event, the detailed information of the event is checked, so that the interesting event can be quickly positioned by the user, and the time for the user to look up the event is saved.

According to the technical scheme of the embodiment of the invention, through displaying the virtual interest points formed by the events in the map, the user can accurately obtain the positions of the events and can know the specific information of the events, wherein the events are related to the positions. Therefore, the problem that a user needs to spend a large amount of time to search the event place is solved.

In order to realize further screening of the successfully matched interest points, the displaying of the successfully matched interest points in the map comprises:

The category of the interest point is preset. The categories may include at least one of travel categories, information categories, and navigation categories.

Specifically, the determination of the keyword category may be implemented by preset keyword matching and/or semantic analysis.

Illustratively, if it is acquired that the search keywords input by the user at least once within the last 2 minutes are "Italian style street" and "five avenues," the search keywords are respectively matched with the preset keywords of each category. And the matching result is that the search keyword is matched with the preset keyword of the travel category, so that the category of the search keyword is determined as the travel category. And then, displaying the interest points which are successfully matched and belong to the travel category.

It is easily understood that such an effect can be achieved by the above steps: the user intention is determined by classifying the keywords continuously input by the user at least once, and then the interest points are displayed according to the user intention, so that the interference of the display of irrelevant interest points on the user is avoided.

Because the event is related to a location, determining at least one event information and its corresponding location based on the obtained virtual information includes:

Specifically, the method for determining the position included in the acquired virtual information may be any one of the methods in the related art. Alternatively, the determination may be based on semantic analysis, or may be based on necessary word setting. This embodiment does not limit this.

Optionally, the method of determining the event information corresponding to the position according to the virtual information may directly determine the virtual information as the event information corresponding to the position. The virtual information may also be further extracted as corresponding event information.

The process of extracting the virtual information may be described as follows: and performing word segmentation and stop word removal processing on the virtual information to obtain a word sequence, performing semantic analysis on the word sequence, and determining event information according to a semantic analysis result.

In order to further improve the user experience, after the successfully matched interest points are displayed in the map, the method further comprises the following steps:

Specifically, based on any method in the prior art, the information of the event associated with the virtual interest point may be combined with the acquired real scene, and the scene of the event may be reconstructed. Typically, the reconstruction of the scene of the event may be implemented based on an Augmented Reality (AR) technology.

Illustratively, by scene reconstruction, such an effect can be achieved: if the event associated with the virtual point of interest is a concert. After the concert is finished, the user arrives at the concert place, and the collected real scene and the information of the concert event are combined through the terminal to reconstruct the scene of the concert scene for the user to experience.

Example two

Fig. 2 is a flowchart of a point of interest searching method according to a second embodiment of the present invention. The present embodiment is an alternative proposed on the basis of the above-described embodiments. Referring to fig. 2, the method for searching for a point of interest provided in this embodiment includes:

s210, determining at least one event message and the corresponding position thereof according to the acquired virtual message.

Wherein the virtual information includes at least one of news information, a note travel note, and history information having a geographical location. The corresponding location is the place where the event occurred.

Typically, the at least one event information and its corresponding location are determined by performing a classification recognition on the virtual information. The non-position information in the virtual information can be identified and classified through article keyword extraction of natural language; for important geographical locations, precise manual intervention is required due to their low impact and number.

Specifically, determining at least one event information and the corresponding position thereof according to the obtained virtual information includes:

S220, taking each event information and the corresponding position thereof as a virtual interest point of an event.

S230, obtaining the search keywords currently determined by the user, wherein the search keywords comprise keywords of event information.

And S240, matching the search keywords with prestored interest points.

Wherein the point of interest comprises a virtual point of interest of an event, and the event is related to a location.

And S250, determining the category of the search keyword input by the user at least once within a set time range from the current moment.

And S260, taking the interest points which are successfully matched and belong to the category as the interest points to be displayed.

And S270, displaying the abstract of the event related to the virtual interest point in the interest points to be displayed in the map.

S280, if the user selects the detailed information of the virtual interest point, displaying the detailed information of the event related to the virtual interest point.

The detailed information of the event associated with the virtual point of interest may be displayed in the form of a card page. Which may contain at least one of pictures, videos, web links and text information of the event.

Further, the user can realize the following functions through the operation of the event detailed information: for example, more associated information can be checked for hot spot information events; and the discount event can be directly issued based on the discount event.

S290, if the user' S selection for reconstructing the scene of the virtual interest point is obtained, combining the information of the event associated with the virtual interest point with the obtained real scene, and reconstructing the scene of the event.

Specifically, for celebrity anecdotal events, scene restoration can be carried out based on augmented reality technology, and the user can obtain experience personally on the scene through the cell-phone screen.

Optionally, the execution sequence of step S280 and step S290 is not limited, and step S290 may be executed before step S280.

Referring to fig. 3, in practical application, the method for searching for a point of interest may be described as follows: collecting virtual information data; identifying and classifying the virtual information data, and determining the position and event information associated with the virtual interest point of the event; pushing the virtual interest points based on at least one of user retrieval behaviors, target locations, time and date and user positions, and displaying the virtual interest points in a map of the user side; the user can realize interactive operation with the event through the world wide web core language Html5 based on the image-text video or the augmented reality technology in the event information.

In practical application, the virtual interest points can be actively pushed to the user. Specifically, besides the retrieval behavior of the user, the user intention can be analyzed by combining the geographic position, the time, the season and other information of the user. For example, when a user is continuously retrieving attraction information, it may be inferred that the user's intent is "looking for a play destination". At this point, virtual points of interest associated with their search targets, such as celebrity stories, news hotspots, etc., may be displayed. For another example, when the user has retrieved a destination by himself, it can be inferred that the user's intention is likely "view location surrounding information". And displaying the virtual interest points around the retrieval destination in the map.

The interest point searching method can achieve the following effects: the method enriches the use scene of the map software by showing the virtual information which is interested by the user in the form of a virtual interest point. The system is not only a traffic information inquiry tool, but gradually becomes a platform integrating travel, sharing, information and the like.

According to the technical scheme of the embodiment of the invention, the user intention is determined by classifying the keywords continuously input by the user at least once, so that the interest points are displayed according to the user intention. And further avoid the display of irrelevant points of interest from causing interference to the user.

It should be noted that, based on the technical teaching of the above embodiments, a person skilled in the art has an incentive to combine the above embodiments to realize the search and display of the virtual interest points of the event.
